During dosing these animals were housed under similar exposure conditions to those animals exposed to the test substances but with a flow of air through the exposure chambers.
The phospholipidic composition of this substance, although partly a barrier, helps to create a mobile intercellular space allowing the flow of substances [ 19].
They are responsible for a whole host functions providing structural rigidity to cells; regulating metabolism; making up the building blocks of the bones, muscles, cartilage, skin, and blood; and controlling the flow of substances that pass through the body's membranes.
To better simulate the body, MIT researchers created a much more complex platform where researchers can put up to 10 organ tissues in separate compartments, regulating the flow of substances and medications between them in real time.
It is established that the growth of nano-gold islands on the single-crystal silicon surface is determined by the flow of substances to the surface and from it (dynamic model).
The balances of the Grid, CHP units, wind power units, the heat supply, coal consumption and reduction are listed in Table 5 for Case 1 Case 4, which could clearly show the flow of substances and energy.
In order to have cell adhesion onto the surface, the bacteria synthesize and release exopolysaccharides, which are considered key components in determining the structure and functional integrity of biofilm, besides acting as adhesives and defensive barrier, protecting the cells from being detached by the flow of substances.
Regardless the cause, mucosal barrier defects determine an increased flow of antigenic substances that challenge the mucosal immune system.
Making a start from successful design experience of closed ecological life support systems, which were initially created for long-duration space flights, our research implements the idea to realize closed circle for flows of substances and energy for utilization of human waste and improving air quality within residential building.
They produce a flow (pressure) of nitrogenous substances that reaches the lake, through agricultural land run off, or through direct or indirect discharge from the sewage system.
